Engine Retrofit Kit 46018

Part Number:46018

Each member company of the Hedman Performance Group is a specialist in the field they serve. Hedman hedders specializes in headers, Trans-Dapt Engine/transmission swap mounts, and Hamburger's focuses on oil pans. Working together, the HP Group companies join as one to develop comprehensive kits that include everything you'll need to safely, and properly, fasten the donor LS engine to the 1968-72 GM A-Body chassis. Sold as a single part number, purchasing complete engine swap kit ensures the products have been developed to work with each other, and takes the guesswork out of choosing swap products.

This Swap-In-A-Box Kit is developed specifically for installing an LS engine and TH350 and TH400 automatic transmission into 1968-72 GM A-Body cars (Buick Skylark, Chevy Chevelle, El Camino, Monte Carlo, Oldsmobile Cutlass, 442, Vista Cruiser, Pontiac GTO, LeMans, Tempest). This comprehensive kit includes a pair of mild steel, satin black ceramic-coated 1-3/4" diameter Mid-Length headers with gaskets, bolts and exhaust adapters, a complete engine mount kit with hardware and rubber pads, and an LS swap engine oil pan with bolts, gaskets and special pick-up tube

Kits for 4L60E or 4L70E auto transmission projects, as well as kits with Hedman's HTC polished silver ceramic-coated, or uncoated headers are also available.

Headers are backed by a limited lifetime warranty. All other components are covered for a full year from the date of purchase.
